ea30f152b7 fetchClosure: Allow input addressed paths in pure mode
When explicitly requested by the caller, as suggested in the meeting
(https://github.com/NixOS/nix/pull/8090#issuecomment-1531139324)

> @edolstra: { toPath } vs { fromPath } is too implicit

I've opted for the `inputAddressed = true` requirement, because it
we did not agree on renaming the path attributes.

> @roberth: more explicit
> @edolstra: except for the direction; not immediately clear in which direction the rewriting happens

This is in fact the most explicit syntax and a bit redundant, which is
good, because that redundancy lets us deliver an error message that
reminds expression authors that CA provides a better experience to
their users.

484290a9e0 Use a struct not std::pair for SearchPathElem
I got very confused trying to keep all the `first` and `second` straight
reading the code, *especially* as there is also another `(boolean,
string)` pair type also being used.

Named fields is much better.

There are other cleanups that we can do (for example, the existing
TODO), but we can do them later. Doing them now would just make this
harder to review.

a0c4d58549 Remove RegisterPrimOp constructor without support for documentation
The remaining constructor RegisterPrimOp::RegisterPrimOp(Info && info)
allows specifying the documentation in .args and .doc members of the
Info structure.

Commit 8ec1ba0210 removed all uses of the removed constructor in the
nix binary. Here, we remove the constructor completely as well as its
use in a plugin test. According to #8515, we didn't promis to maintain
compatibility with external plugins.

Fixes #8515

1ad3328c5e Allow tarball URLs to redirect to a lockable immutable URL
Previously, for tarball flakes, we recorded the original URL of the
tarball flake, rather than the URL to which it ultimately
redirects. Thus, a flake URL like
http://example.org/patchelf-latest.tar that redirects to
http://example.org/patchelf-<revision>.tar was not really usable. We
couldn't record the redirected URL, because sites like GitHub redirect
to CDN URLs that we can't rely on to be stable.

So now we use the redirected URL only if the server returns the
`x-nix-is-immutable` or `x-amz-meta-nix-is-immutable` headers in its
response.

8ec1ba0210 Register all PrimOps via the Info structure
This will allow documenting them (in later commits).

Note that we keep the old constructor even if it is no longer used by
Nix code, because it is used in tests/plugins/plugintest.cc, which
suggests that it might be used by some external plugin.

Parse TOML timestamps (#8120)
Currently `fromTOML` throws an exception when encountering a timestamp
since the Nix language lacks a way to represent them.

This patch changes this beaviour and makes `fromTOML` parse timestamps as
attrsets of the format

  { _type = "timestamp"; value = "1979-05-27T07:32:00Z"; }

This is guarded by an experimental feature flag to leave room for iterating on the representation.

primops: lazy evaluation of replaceStrings replacements
The primop `builtins.replaceStrings` currently always strictly evaluates the
replacement strings, however time and space are wasted for their computation
if the corresponding pattern do not occur in the input string. This commit
makes the evaluation of the replacement strings lazy by deferring their
evaluation to when the corresponding pattern are matched and memoize the result
for efficient retrieval on subsequent matches.

The testcases for replaceStrings was updated to check for lazy evaluation
of the replacements. A note was also added in the release notes to
document the behavior change.

98afd6ff76 Delete commited build artifacts
They were improperly added in 8a93b5a551.

They were not `.gitignore`d because they were stale in that commit --
build artifacts no longer used that name by then and so `.gitignore` was
updated accordingly.

bbd7d5de09 Fix some bounds in rapid check instances
`inRange` is exclusive not inclusive:
https://github.com/emil-e/rapidcheck/blob/master/doc/generators.md#usage

Furthermore, use `std::variant_size_v` so we use the right number
automatically.

Finally, make the `switch` assert the discriminant is in bounds as
expected.
